All the other bookies paid normally (as they should) since the bets are won except FortuneJack and similar layout sportsbook ,according to who "the odds were incorrect so the bets get voided".
Can you share your bet slip of the other sportsbooks where you had placed the bet on the same betting event at the same time? BTW, you are complaining about FortuneJack and other sportsbook with the same layout. It means, you are complaint is against
Betby odds provider. FortuneJack sportsbook odds provider is Betby, and all other platforms have the same layout where the odds provider is Betby. Therefore, the decision has been made by the odds provider Betby if your bets have been cancelled in the same way on other platform like FortuneJack.
